why is jquery ajax not sending the data in get request

Question

I'm setting up a page where our staff can view a list of items that should be on the shelf and then confirm if the items are there, or send in an alert if there's a problem.

I'm trying to create one function for each situation (item present, item not present, information incorrect) where each function will pass the correct parameters for that situation to a generic function which will make the actual ajax request.

This function is triggered by a button click (when the item is present and correct) and it logs the data correctly:

function log (rec_id,offset) { console.log("On Shelf \r\nRecord_Id: "+rec_id+"\r\nOffset: "+offset); var rdata =[]; rdata['id'] = rec_id; rdata['status'] = 1; rdata['branch'] = $("#branch").val(); rdata['loc_code'] = $("#location_code").val(); console.log("log function"); console.log(rdata); log_item(rec_id,offset,rdata); }

this is what is output to the log:

[id: 1833049, status: 1, branch: "1", loc_code: "mnlp"]

the log_item function makes the ajax request

function log_item(rec_id, offset, rdata) { console.log("Logging Item: i"+rec_id+"a"); console.log("log_item function"); console.log(rdata); $.ajax({ url: 'logItem.php', data: rdata }).done(function(response){ console.log(response); $("#form").foundation('close'); }); }

It too logs the data correctly

[id: 1833049, status: 1, branch: "1", loc_code: "mnlp"]

But when I view the requests sent, these parameters are not getting passed in request.

Is there a reason GET won't work? I wrote logItem.php to retrieve the parameters from $_GET ? — cdm014

Shouldn't it be an object instead of an array? I don't think [] is going to be passed as an object. — Fernando de Bem

@misher jQuery converts its to a query string and appends it to the URL. api.jquery.com/jQuery.Ajax — gre_gor

i think the problem is here.

var rdata =[];

Change it to

var rdata ={};

That did the trick. From what I understand, that changes it to an object instead of an array, any idea why the array didn't work?

javascript does not support associative array. array can have only index like 0,1,2 .(always numeric). For storing key value js has object.

@cdm014 The jQuery ajax function uses jQuery param to convert the data into the query string for a GET request: api.jquery.com/jquery.param. As you can see from the documentation, it supports array as an input type, but you passed in an empty array (length == 0), so it produced nothing.
